My e-mail service is accessed through BT Yahoo's web page. At about midday today (Uk time) my contacts received e-mails purporting to be from me saying I was stuck in the Philippines without money, and telephoned me. When I opened my mailbox, everything I had received since March had disappeared (but I later found it in Trash) and my entire Sent box had also disappeared. One contact of mine who replied had a reply from the hacker!
I changed the password immediately this happened, but not the security question, as the BT instructions didn't suggest that. I've dealt with the bank and other urgent things. I've asked friends to send me e-mails, but they don't come through. Sending doesn't work either, and my i-Pad (the settings of which I changed to the new password) is now showing a message saying the password or username is incorrect.
You weren't listening-- I changed the i-Pad password. When I try to send nothing happens, and nothing appears in my Sent box. On the i-Pad there are three of my attempted messages in the outbox.
